Introduction
The main purposes of chronic otitis media (COM) surgery are to
re-establish the protective barrier of the middle ear and improve
hearing. However, current study results vary significantly since the
comparability of surgical results can be affected by variances in
surgical method, repair materials, lesion severity, and so on. Pure tone
audiometry is routinely used to assess pre-and postoperative hearing.
Most clinical research, on the other hand, have only assessed average
pure tone threshold, rather than frequency-specific hearing results.
Frequency-specific hearing studies are important since the same average
pure tone threshold does not always lead to the same patterns of hearing
perception 1. Therefore, we conducted a retrospective
study in which we assessed frequency-specific hearing results based on
possible influencing factors to give evidence for frequency-specific
postoperative hearing rehabilitation.
